5.82 Write a balanced equation to describe any acid-base
neutralization reaction that might occur when the
following substances are mixed.
(a) H (3) and KOH(aq)
(b) H. PO,(aq) and NaOH(aq)
(c) H2SO4(ag) and Fe(OH)2(s)

If two objects at different te,peraure are in contact with each other what happens to their temperature

Given the following at 25c calculate delta hf for hcn (g) at 25c. 2nh3 (g) +3o2 (g) + 2ch4 (g) > 2hcn (g) + 6h2o (g) delta h rxn= -870.8 kj. delta hf=-80.3 kj/mol for nh3 (g), -74.6 kj/mol for ch4, and -241.8 kj/mol for h2o (g)

In an exothermic reaction at equilibrium, what is the effect of lowering the temperature? a. the reaction makes more products. b. the reaction makes more reactants. c. the reaction is unchanged.
